Expertise and Experience

Ben’s practice focuses on the chemical, chemical engineering and life sciences sectors.  He has particular expertise in the fields of air and gas separation, cryogenics, combustion, syngas, semiconductor manufacture, new chemical entities, chemical formulations, pharmaceuticals and medical treatments, protein and nucleic acid synthesis and purification, and antibodies.

Ben acts directly for a number of multinational corporations, and in this capacity he regularly drafts applications for filing before the US, European and International Patent Offices; prosecutes cases before the European and International Patent Offices; and consults on the prosecution of cases in the USA, Japan, China, India and elsewhere.  Ben defends his clients’ patents and challenges competitors’ patents in opposition and appeal proceedings before the EPO; and provides patent landscape, infringement and freedom to operate opinions.  He also works with several small and medium-sized companies, advising them on, and handling, all aspects of their patent portfolios.

After obtaining a Masters Degree in Intellectual Property (being one of only two candidates in his year to obtain a pass with distinction), Ben joined the profession in 1999, and qualified as a European Patent Attorney in under three years.  For many years he has also been an active member of the Life Sciences Committee of the Chartered Institute of Patent Attorneys (CIPA), whose remit includes advising the UK government and other international bodies, providing training to CIPA members, and providing educational publications on IP matters, in the Life Sciences field.


The Legal 500 UK 2022 edition recommends “head of life sciences practice, Ben, whose experience includes transactional and licensing work in addition to original drafting and prosecution in the UK, at the EPO and in the US” as a leading patent attorney for his "in-depth knowledge of medical devices and pharmaceuticals and is noted as being very strong in patent law". Clients note that "Ben Muir is highly skilled technically and legally diligent, detail-oriented, and a pleasure to work with".
